BUMPER.

Tt is an object ot this invention to provide a bumper composed ot' twobumper bars and `tivo back bars7 with the bach bars united at one end tothe ends ot thebuinper bars and with their other ends united to thecentral part ot the bumper bars in such a Way as to have a slidingmotion. These bars are held 1n relation to cach other by bolts and nuts,together With suitable clamping members.

ln the accompanying drawings there kis shown a preferred embodiment otthis invention, which is here used by Way of illustration.

Figure l is alplan vievv of the bars assembled. Y

Figure 2 is a :trent view showing .the lnunper bars and the attachingplates.

Figure 3 is a plan view of one end ot the bars. i

Figure d is a l'ront view of the parts shown in Figure 3.

Figure 5 is a section on the line 5--5 .of Figure fl. i

Figure 6 is an enlarged iront vieu7 ot the middle plate. y

Figure 7 is a vertical section showing the means by which the inner endsot the back bars are attached to the iront bars.

Figure 8 is a cross section through the middle plate showing the meansby which the bars are connected at that point.

Figurel shows the parts of the bumper assembled in Whichthe numeral 1indicates the tivovtront bumper bars proper. Thesebars are curved ateach end, as indicated by the inuneral 2, and have holes 3 therein `forthe reception ofi lugs or studs. i i y The back bar 4l is composed oftivo sections. The outer end oi' cach section has a hole 5 therein forthe reception otl the bolt, by which it is attached to the outer ends otthe :trent bars. Each of these back bar sections is pro-` vided, at itsinner end, with a hole 6. AThe outer ends of these bars are attached tothe front bars by means et a casing which has a hole 8 therein. Thishole is located in the central part ot the casing, and on each end oiethe casing there is provided a stud mem ber 9, which is adapted to enterthe holes in the ends of the two front bars.

Each of the casings 7 is provided with side flanges l0, which overlapthe side edges ot the bars at the ends thereoi". These casings also bendbaclrWardly, as indicated by the numeral 11, at the end,so as to aloi'da glancing action when the ends of the bumper engage any object. y

Each end casing is also provided with a projection 12 adapted to litbetween the iront bars and hold them in spaced relation. while the endsOt said bars are engaged by the casing and held by the studs 9 in theholes 3.

For the purpose of holding these parts iu assembled relationthere is abolt 13, which passes through the casing 7 between the two i'ront barsand through the hole 5. This bolt is held in assembledpcsition by meansof a nut 14, and for the purpose ot preventing` the nut becoming loosethere is provided a lochvvasher 15. The parts are united at the centeret the front bars by means oit' a plate 1G. This plate has projectingfrom the central part thereof aspacing stud 17 and has a bent part- 18at each end, which engages the outside edges o1 the iront bars.

The plate 16 has a hole therethrough 19p adapted to receive a bolt 20.The bars are heldin position by means of a clamping plate 21, Which hasa hole therein 22, adapted to receive the bolt 2U. This clamping platehas the sides thereoi3 bent down, as indicated by the numeral 23, toengage the outside parts of the inner ends of the back bar. lllhen thebolt 20 is placed in position through the platel and the clamping plate21 there is engaging the end thereof a nut 24. This nut is heldagainstturning on said bolt by means of a lockivasher 25. y y

`llVhen the parts are assembled, as shown in Figure l, the outer ends ofthe bars are held in :liXed` relation to each other by means of thebolt, and the studs in the end casings. The inner ends of the bach barsare held in sliding relation with the front bars. `This is et- ;tectedbecause the holes in the inner ends ot the back bars are elongated andpermit a longitudinal motion thereof on the stud 2G litting in theseholes.

It will also be observed that intermediate parts of the back bars, thatis parts between the'center and each end of the bumper, are spaced fromthe front bars. This affords a strengthening effect and affords means byWhich the bumper may be attached to the automobile. l

f Letters Patent, is:

l'. In a bumper, a front bar, a back bar composed of sections, oneend ofeach section rigidly attached to one'end of the front bar and the otherend of each section slidably attached to the front bar for independentsliding motion.

2. In a bumper, a front bar, a back bar composed of sections, one end ofeach l section rigidly attached to one end of the front bar and theother end of each section slidably attached to the middle of the frontbar for independent sliding motion. y

3..In a bumper, a pair of bumper bars, a back bar, means to engage allofsaid bars to hold said bumper bars in spaced relation to each other andthe back bar in contact with the bumper bars so as to have onlyalongitudinal sliding motion on the bumper bars.

4. InA al bumper, a pair of bumper bars, a back bar composed ofsections, each section`having a hole in one end thereof, and means tohold the bars in relation to each other, including means fitting in saidholes to permit movement of each section in relation to the other and-to said pair ofbars.

5. Inja bumper, a pair of `bumper bars arranged in spaced'relation toeach other,

a backbar composed of sections, each sec'- 'tion having Van elongatedhole in the end thereof, a front plate engaging said air of bumper barsandadapted to hold said bars mspaeed' relation to each other, ak secondVplatefhaving'studs'thereon adapted to engage the holes in saidsections, andmeans engaging said plates to hold them in relation to saidbars. l

k6. In'a bumper, a pair of bumper bars held ingspaeed parallel relationto each other, a back bar composed of two sections, one end of eachsection being fastened'to one end of said pair of bars, and the otherend of each of saidv sectionsjbeing 'astened to the middle ofsaid pairof bars 'so as to have movement to and from each other and longitudinalmotion with relation to said pair'of bars.

A '7.'y In a bumper, a pair ofA bumper bars, each bar having a hole inone end thereof, a

back bar having a hole in one end thereof, a. casing having studsthereon fitting in the holes in said bumper bars and a central holetherein, and means passing through the hole in the casing and the holein the back bar and adapted in cooperation with said casing to hold thebars in relation to each other.

8. In a bumper, a pair of bumper bars arranged in spaced parallelrelation to cach other, each bar having a hole in one end thereof, aback bar having a hole in one end thereof, said end in engagement withthe hole end of said pair of bumper bars and across the spacetherebetween, a casing having studs thereon to engage the holes in saidpair of bars and having a hole therein, and a bolt passing through thehole in the casing and the hole in the back bar to hold said bars infirm engagement with each other.

9. In a bumper, a bumper bar having a substantial bend at each end, aback bar coinposed of sections having an end of each section bent and inengagement with the bent parts of the bar, means substantially inclosingsaid ends of said bars and adapted to hold them in fixed relation toeach other, and means to engage said bumper bar and the other end ofeach section to hold said ends in contact with said bar so that saidends may have longitudinal movement on said bumper bar.

l0. In a bumper, a pair of bumper bars, each bar having a substantialbend at each end thereof, a back bar composed of sections each havingone end thereof bent and in cngagement with one bent end of each of thepair of bars, means substantially inclosing said ends and adapted tohold them in fixed relation to each other, and means engaging saidbumper bars and the other ends of said sections to hold said ends incontact with the pair of bars so that said ends may have longitudinalmovement on said bumper bars.

11. In combination in a bumper, spaced front bars, a pair of rearaligned bars located intermediate the horizontal planes of the frontbars and in partial overlapping relationship, and a clamping membersupport extending between the front bars adapted to engage the front ofthe front hars and the rear of the inner ends of the rear bars slidably.

In testmonv whereof, I aix my signature.
